How we calculate the Trust Score

Every company starts at 100

We subtract points for each missing requirement or risk factor. Verified means all the core requirements for that company's type pass. Nothing is added back, the score is a deduction model built only on public FMCSA data. No pay-to-play, no opinions.

Requirements differ by company type

Each company is judged fairly on its own FMCSA obligations. Anything that doesn't apply shows as a grey N/A, not required, never a penalty.

Carrier (for-hire)

Operating authority, authorized-for-hire, insurance on file, safety rating.

Broker

Broker authority + $75k surety bond (BMC-84/85). MCS-150 not required (no fleet).

Freight forwarder

FF authority + $75k bond + BOC-3. MCS-150 not required (no trucks).

Private carrier

Active USDOT + MCS-150 + safety. No operating authority / for-hire / insurance filing required (hauls its own goods).

Crashes are scaled, not flat

Crash history is proportional. We don't apply a flat penalty, we scale it to (a) crashes per vehicle in the fleet and (b) the share of those crashes that were fatal. So a big, safe fleet barely moves; a small fleet with many (and fatal) crashes takes a large hit.

0 pts deductedscaled by rate & severityup to −28 pts

Low end

50,000 vehicles + 1 crash → ~0 pts. A huge fleet with very few crashes per vehicle is almost untouched.

High end

5 vehicles + 3 crashes incl. fatal → large deduction (near the −28 cap). Many crashes per truck, fatal-heavy.

Mechanics: deduction is capped at 28 points, weighted roughly 60% on crashes-per-vehicle and 40% on the fatal ratio. Zero crashes = zero deduction. If fleet size is unknown, only crash severity can move the score (conservative).

Out-of-service rate vs. the national average

Driver and vehicle out-of-service rates are measured against the FMCSA national average, not a flat number. A company only takes the deduction when it sits above the national benchmark, for example “Vehicle OOS 37% vs national avg 20.7%”.

Point reference, the full menu

Every factor and exactly how many points it can remove. Knockout factors (they also fail Verification) are marked.

Factor	Points
USDOT / authority not active with FMCSA knockout	−25
Missing operating authority (when required) knockout	−15
No insurance or surety bond on file (when required) knockout	−25
Unsatisfactory safety rating knockout	−30
Conditional safety rating	−12
MCS-150 biennial update overdue (carriers)	−10
Crashes, rate-adjusted (per-vehicle & fatal share)	0 to −28
Driver OOS rate above national average	−5
Vehicle OOS rate above national average	−5
Very new carrier (under 1 year)	−10
Limited operating history (1-3 years)	−6
Moderate operating history (3-5 years)	−3
Operating history unknown	−3
No public phone number	−3
No public email address	−2

All inputs come from public FMCSA records (operating authority, insurance/bond filings, the SAFER/SMS safety profile, crash & inspection reports). If FMCSA updates a record, the score updates with it. For the full deduction table, see the methodology page.
